My Cartesian printer is gaining 2-mm on Z after homing and moving into the print area. Needless to say the prints aren't sticking.

This is a new built printer and all other features are working now that I have gone to Marlin 1.1.7 See attached configs.

Well the cat gets me again.

I am still seeing a 1mm rise in Z after homing before 1st layer.
